Abstract :
A cascade raster system will be used in Hall C at CEBAF to generate a variable rastering pattern on the polarized target, the cryogenic hydrogen target, and the beam dump with an adjustable frequency up to 10 kHz and a variable deflection angle from 0.05 mr to 1 mr. Each raster consists of two air-core bedstead coils providing transverse and vertical scans. The magnets are energized by individual MOS power amplifiers controlled by a scan generator which determines frequency amplitude, and the phase shift between the cascade rasters
